  • Hi EvginI,
    As official document said, the new preview version of the .NET Core Windows Forms designer is available with the Visual Studio 16.5 Preview 1.
    So you must be using Visual Studio 16.5 Preview 1 or a later preview version.

  • Hi EvginI,
    To use the designer, you must be using Visual Studio 16.5 Preview 1 or a later version.
    You need to enable the designer in Visual Studio. Please follow the steps: Go to Tools > Options > Environment > Preview Features and select the Use the preview Windows Forms designer for .NET Core apps option.
    More details you can refer to this document.
